Big Brother replaced 2+2=4 with 2+2=5:

"In the end the Party would announce that two and two made five, and you would have to believe it. It was inevitable that they should make that claim sooner or later: the logic of their position demanded it. Not merely the validity of experience, but the very existence of external reality, was tacitly denied by their philosophy. The heresy of heresies was common sense. And what was terrifying was not that they would kill you for thinking otherwise, but that they might be right. For, after all, how do we know that two and two make four? Or that the force of gravity works? Or that the past is unchangeable? If both the past and the external world exist only in the mind, and if the mind itself is controllable what then?"

Einstein replaced Newton's absolute time with an absurdity called spacetime:

"Special relativity is based on the observation that the speed of light is always the same, independently of who measures it, or how fast the source of the light is moving with respect to the observer. Einstein demonstrated that as an immediate consequence, space and time can no longer be independent, but should rather be considered a new joint entity called "spacetime." http://community.bowdoin.edu/news/20...rs-of-gravity/

Scientists in Big Brother's world may be trying to reconcile 2+2=4 and 2+2=5.

Scientists in our post-truth world are trying to reconcile Newton's absolute time and Einstein's spacetime:

"The effort to unify quantum mechanics and general relativity means reconciling totally different notions of time. In quantum mechanics, time is universal and absolute; its steady ticks dictate the evolving entanglements between particles. But in general relativity (Albert Einstein's theory of gravity), time is relative and dynamical, a dimension that's inextricably interwoven with directions X, Y and Z into a four-dimensional "space-time" fabric.." https://www.quantamagazine.org/20161...-time-problem/

Almost all theoreticians find Einstein's spacetime unacceptable - they want to modify and even totally reject it. This is silly. Spacetime is a consequence of Einstein's constant-speed-of-light postulate so if you don't accept it in its present form and want to modify, let alone reject, it, you should first declare that the postulate is false. Logic does not allow the combination "true postulate, unacceptable consequence":

"Special relativity is based on the observation that the speed of light is always the same, independently of who measures it, or how fast the source of the light is moving with respect to the observer. Einstein demonstrated that as an immediate consequence, space and time can no longer be independent, but should rather be considered a new joint entity called "spacetime."
